My PO4 is measuring low on the Hanna around 0.05 but I think it's quite a bit higher as there is a film of algae around the sandbed glass and a light film of it on the rocks, not a lot but it's there, wondering how much Rowa to use? as following the instructions I'm using the correct about but it's not taking into account the PO4 the algae is using.
Should I up the amount until this thin film goes? Or is that a cuc issue and I shouldn't expect a "algae film free tank"? And just buy some more cuc?
